SPECIFICATION formingpart of Letters Patent No. 272,080, dated February 13, 1883,

r Application filed September 22, 1882. (No model.) i

To all whom it may concern:

Be it known that I, ALBERT N. NoRRIs, a resident of Rushville, in the county of Bush and State of Indiana, have invented a new and useful Improvement in Cultivators, of which the following is a specification, having reference to the accompanying drawings.

My invention relates to that class of cultivators in which the frame consists of laterallymovable wings carrying cultivator-hoes hinged thereto, said wings being jointed atone end to a central draft-beam and capable of lateral adjustment at the other end, and in which an adjustable gage governs the depth to which the hoes may enter the earth.

The object of my invention is to firmly sustain the cultivator-hoes against lateral strain.

My invention consists in the means used to accomplish the above-mentioned object, which means are hereinafter clearly shown and described, and particularly pointed outiu the claim.

The accompanying drawings illustrate my invention.

Figure l is an elevation. Fig. 2 is a plan. Fig. 3 is anelevation on an enlarged scale of one of the hoe-supports. Fig. 4 is a similar section of the same. Fig. 5 is a plan on an enlarged scale of the wing-adjusting device. Fig. 6' is a vertical section.

Like letters refer to the same partsin the several figures.

To a central draft-beam, a, are hinged side wings, b b, in the manner usual in this class of implements. Mounted iipon the rear end of beam or. is a segmental gear, 0, the hub of which forms journals which rest in hearings in plates 01 and 0. Plate d is provided with two V upwardly-projecting lugs,fand g, which serve as supports for plate 6, and also for bearings against which racks hand 11 slide. Racks h and 'i engage the gear 0, and are extended to form arms which are pivoted to wings I) b, as shown. To the center of gear 0 one end of a vertical shaft, j, is secured, to the upper end of which a. crank, 70, is attached in such manner thatits outer end may be raised sufficiently to clear the projections in a notched segmental frame, Z, which is attached to and between the plow-handles m. Frame Zis a casting of iron having a notched segment, a, a cross-bar, o, forming a bearing for the upper end of shaft j,

centrally located in relation to said segment, and flanges p, by which it is secured to the plow-handles m, the whole arrangement being such that wings I) b are simultaneously swung from or toward the central beam by means of the crank it, partially revolving shaft j and gear 0, and thereby moving racks h and i. The tendency of wings I) to draw together toward the central beam is resisted and prevented by" crank is engaging one of the notches in frame I.

The draft attachment and depth-gage consists of two brackets, r, permanently pivoted to the dralt-beam just in front of the wings b, and adj ustably securedto the front end of the'loeani by means of a bolt passingthrough a slot, 8, in said brackets. Brackets r are adapted to receive between them, at their lower ends, below the beam, at friction-wheel, t, and are also provided with a seriesof holes, 3 above the beam, forming a clevis for the reception of the draft-hook u. v

The hoes are attached to the under side of the wings and center beam by means of a plate, a, to which they are hinged between lugs a, and are prevented from swinging by a Wooden break-pin passing through lugs y and the hoe-shank. In order that thelioes may swing easily when they meet an obstruction sufficientto break the pins, it is necessary that they should fit somewhat loosely between the lugs forming the hinge and between those forming the break-pin support, and they are then liable to twist over more or less sidewise. 'lo correct this difficulty, I provide on plate 17 an additional pair of narrow lugs, to, which are centrally located between the hinge and the breakpin supports. Said lugs are made to lit-closely to the shank of the hoe, so as to support it against lateral strain.

I claim as my invention In a cultivator, the combination, with plate '0, provided with hinge-lugs w and break-pin lugs y, adapted to titloosely over the hoe-shank, of lugs to, located between said hinge-lugs and break-pin lugs, and adapted to embrace and fit closely over the hoe-shank, in the manner shown and described, for the purpose set forth.

ALBERT N. NORRIS.
